Low Separation Force Watertight Connectors

Abstract

The invention discloses a watertight connector of a low separating force, and the connector can be used for cable connection between a power cabin and a recoverable cabin of recoverable acoustic UWSN nodes. The watertight connector comprises an upper installation body and a lower installation body, the upper installation body is installed in the recoverable cabin, and the lower installation body is mounted in a structural body of the power cabin. A traditional pin-and-jack type watertight connector realizes sealing via interference fit between pins and jacks, the axial resistance is high during separation, and separation cannot be realized without labor force or other auxiliary devices. When the watertight connector of the low separating force is in a connected state, a preload spring ensures reliable electrical connection between a copper cone and a copper cap of a conductor, and non-rigid connection is characterized by that cables are not broken during separation, the separating force is low, separation is rapid, and the sealing performance is high after separation.

Description

technical field [0001] The invention relates to the field of underwater connectors, in particular to a watertight connector with low separation force. Background technique [0002] Underwater wireless sensor network (UWSN) can achieve three-dimensional, real-time and continuous observation of the ocean, and has important applications in water environment monitoring, marine data collection, seabed detection, disaster forecasting, etc. The underwater sensor network node is the basic unit of the underwater sensor network. The nodes form a network through a certain topology structure to realize the observation of the target sea area. Due to the particularity of the underwater environment, the underwater sensor network nodes are generally powered by batteries, and the energy consumption of underwater acoustic transducers is high. In order to achieve relatively long-term observations, the network nodes need to be equipped with large-capacity batteries. It is difficult to arrange ...

Problems solved by technology

At the same time, the deployment and recovery of underwater sensor network nodes can be completed by divers in relatively shallow sea areas. When the water depth increases, it is generally completed with the assistance of ROV, and the economic cost is high.
